在日语情态表达中，同一形式存在多种语义，并且这些意义之间存在相关性，本文以「してはいけない」为例，结合日本国立国语研究所的《现代日语书面语均衡语料库》少纳言语料库，从语用学角度分析其使用条件，并根据其语义扩展找出情态表达形式的扩展顺序，对日语教学提供相应的理论依据。
Multiple semantics in the same form is rather common in Japanese modal expression. And there is a significant correlation between these expressions. In this article, taking “shit e ha i ken a i” as an example, we analyzed the application conditions of the same form from the perspective of pragmatics based on the “National Japanese Written Equilibrium Corpus” launch by the National Institute of Japanese Languages. We also find the extension order of modal expression forms according to the semantic extension. This provides a sound theoretical basis for Japanese teaching.
